adb shell    // Open or run commands in a terminal on the host Android device.

== Devices
adb usb
adb devices   //show devices attached
adb devices -l //devices (product/model)
adb connect ip_address_of_device

== Get device android version
adb shell getprop ro.build.version.release 

== LogCat
adb logcat
adb logcat -c // clear // The parameter -c will clear the current logs on the device.
adb logcat -d > [path_to_file] // Save the logcat output to a file on the local system.

=== Few bash snippets ===
@Source (https://jonfhancock.com/bash-your-way-to-better-android-development-1169bc3e0424)

=== Using tail -n
//Use tail to remove the first line. Actually two lines. The first one is just a newline. The second is “List of devices attached.”
$ adb devices | tail -n +2

=== Using cut -sf
// Cut the last word and any white space off the end of each line.
$ adb devices | tail -n +2 | cut -sf -1

=== Using xargs -I
// Given the -I option, xargs will perform an action for each line of text that we feed into it.
// We can give the line a variable name to use in commands that xargs can execute.
$ adb devices | tail -n +2 | cut -sf -1 | xargs -I X echo X aw yiss

=== Three options below together
// Will print android version of all connected devices
adb devices | tail -n +2 | cut -sf -1 | xargs -I X adb -s X shell getprop ro.build.version.release  

=== Using alias
-- Example 1 
alias tellMeMore=echo
tellMeMore "hi there"
Output => hi there
-- Example 2
// Define alias
alias apkinstall="adb devices | tail -n +2 | cut -sf 1 | xargs -I X adb -s X install -r $1"
// And you can use it later 
apkinstall ~/Downloads/MyAppRelease.apk  // Install an apk on all devices
-- Example 3
alias rmapp="adb devices | tail -n +2 | cut -sf 1 | xargs -I X adb -s X uninstall $1"
rmapp com.example.myapp // Uninstall a package from all devices
-- Example 4
alias clearapp="adb devices | tail -n +2 | cut -sf 1 | xargs -I X adb -s X shell pm clear $1"
clearapp com.example.myapp  // Clear data on all devices (leave installed)
-- Example 5
alias startintent="adb devices | tail -n +2 | cut -sf 1 | xargs -I X adb -s X shell am start $1"
startintent https://twitter.com/JonFHancock // Launch a deep link on all devices


Setting up your .bash_profile
Finally, to make this all reusable even after rebooting your computer (aliases only last through the current session), we have to add these to your .bash_profile. You might or might not already have a .bash_profile, so let’s make sure we append to it rather than overwriting it. Just open a terminal, and run the following command

touch .bash_profile && open .bash_profile

This will create it if it doesn’t already exist, and open it in a text editor either way. Now just copy and paste all of the aliases into it, save, and close.

alias startintent="adb devices | tail -n +2 | cut -sf 1 | xargs -I X adb -s X shell am start $1"
alias apkinstall="adb devices | tail -n +2 | cut -sf 1 | xargs -I X adb -s X install -r $1"
alias rmapp="adb devices | tail -n +2 | cut -sf 1 | xargs -I X adb -s X uninstall $1"
alias clearapp="adb devices | tail -n +2 | cut -sf 1 | xargs -I X adb -s X shell pm clear $1"

Thank you so much!

Thank you very much love it !!!

love it...

thanks!

These are great. Especially adb bugreport! Here is a few goodies for your .bash_profile

alias adbimg='cd && adb shell screencap -p /sdcard/screencap.png && adb pull /sdcard/screencap.png'
alias adbrec='cd && adb shell screenrecord --verbose /sdcard/adb.mp4'

Thank you so much for sharing :)

Thanks alot.bro

Hi Can you tell me how to copy my host .android/adbkey.pub key inside the android device

Great summary

First off, this is great! Thanks so much for sharing! I wanted to perhaps suggesting the following change for line 106:

adb shell input keyevent 26 // Lock/Unlock android device. It will toggle device screen ON/OFF.

The existing language confused me as I thought it actually powered down my entire device and then could also power it on (something that adb can't do unfortunately afaik).

Would like to request a command to use ADB to clear all text messages on my phone. I would like to programmatically clear messages somehow.

I found out how to do it

pm clear com.android.providers.telephony

Pretty nice! Thanks a lot!

I am trying to run/retrieve info on all the different available options for "content query", for example:

content query --uri content://settings/global

Which is dependent on the URI being of a valid content provider on the device. However, all I can find online are fixed lists for the "content://settings/global" but from my understanding, the value used here are specific to the phone, the apps installed etc. I have not found a shell command that will list valid content providers, on the device. eg https://github.com/jenzz/ContentProviderHelper

Anyone know how to get a list of all the valid URI's (content providers) on the running device using a shell command?

It's also possible to specify shared preferences file.
adb shell 'am broadcast -a org.example.app.sp.PUT --es name Game --es key level --ei value 10'

Is this really writing to a different file though?

Changing shared preference via broadcasts requires https://github.com/jfsso/PreferencesEditor

Is it possible to get copped text string from android device through adb?

Is there any adb command to launch trusted certificate in settings app for android ??? Since that trusted certificate position keeps changing on OS version .

Need solution ASAP .

Thanks in advance,

Excellent work, Thank you

So far this is the best compilation. Thanks for sharing!

Is there any updated adb command for this: adb shell settings put secure enabled_notification_listeners ?

how to create a contact if not exist using adb shell?

Can we open a particular application thru adb commands?

Can we open a particular application thru adb commands?

Yes, it is actually pretty easy, this is one of the possible ways: adb shell monkey -p <insert-package-name> -c android.intent.category.LAUNCHER 1

If you are interested in more ADB inspiration, see my repo https://github.com/IntergalacticPenguin/mobile-toolkit

Can we open a particular application thru adb commands?

What do you mean by open? if you mean to launch a particular application main activity through adb use this:
adb shell am start -n packageName/Activity

For example below command will launch the dialer app on Sony phone:
"adb shell am start -n com.sonyericsson.android.socialphonebook/.DialerEntryActivity"

yes, this worked! adb shell am start packageName,

I again have one more question, can we click a particular email inside gmail ( android emulator ) through adb commands?

possible to get an avd emulator's name?
found this on web, but it does not print out anything
adb -s emulator-5554 emu avd name
thanks

@jdougit
I suggest using adb shell dumpsys, more info here: https://stackoverflow.com/questions/11201659/whats-the-android-adb-shell-dumpsys-tool-and-what-are-its-benefits

thanks, @IntergalacticPenguin
got a solution: (use in a shell script)

name=`(sleep 0.5; echo 'avd name') | telnet localhost 5554 | sed '6!d'`

hi, how to get condition Lock/Unlock device ?

Hi Team,
I need small help

My scenario:

1. I wanted to run one full charge cycle in one of Android phone with Wall charger through ADB shell

I am using below method

1. Boot device to HLOS
2. Connect PC cable and check adb devices
3. once adb devices works I have created shell script which I am running
   command used : adb shell "sh ./ 1 /data/local & "
4. I see script run in background but somehow I am not getting full logs through adb

I also check pid and it was running as process but not sure why I don't get 3~5 hours full logs because this is big time affecting my test results.

Any idea how to resolve this issue?

Is there any possibility to create custom adb command??

Is there any possibility to create custom adb command??

Of course, you can do anything you want - just create your own shell script.

Thank you.
Could you provide me proper steps of how to create a custom adb command in the AOSP build system or provide any reference for the same.

Maybe I dont fully understand what you want to achieve. I have thought, that you wanted to do some work using adb via single command.

What command do you hope to create?

Maybe I dont fully understand what you want to achieve. I have thought, that you wanted to do some work using adb via single command.

What command do you hope to create?

I have a created a socket based channel through which my application gets some data.
In real case this socket gets input from some sensor.
But I would like to create an adb based command to communicate with that socket, just for simulation purpose.
(I don't want to use intents or other such things)

Thanks in advance!!

What does adb -s do??

Adb -s specifies the target for the command to be executed on.
For example you get:
"List of devices attached
Emulator-5554
devaed207"

As an return from "adb devices" then you can specify the device to target with your next command with: adb -s emulator-5554 shell echo "hello".
So in this example your command will be executed on the emulator.

I Love it Thanks

@Pulimet

I think the command to list all the packages should be like this: https://gist.github.com/bbsusheelkumar/357c62202bda3d905d589046b95d157b/revisions

I have tested it and after changes it is working.

cool! Thanx!

Thanks mates

To simulate text with spaces, the space must be escaped, as so:

adb shell input text "some\ text"

so, corrected in the above gist should be:

adb shell input touchscreen text "Wow,\ it\ so\ cool\ feature"

here is a really usefull work you've done. Many thanks.

guys
i just want to ask here

is there an adb command that would allow me to open apps in floating mode or pop-up view?

i just want to ask here

Open a window for each application in linux or windows? I have no idea, but you can use scrcpy to see your full screen inside windows or linux.
Edit: and you can control the screen with the mouse, and type with the keyboard if I'm not wrong.

Hey thanks for the list.
I want to install an apk from /sdcard partition. I tried adb shell pm install < path of apk on device > but that resulted in Unable to get size of:/sdcard/app.apk what am I missing?

is there any ADB command to check dut is latched to the network or not??

adb shell ifconfig

Thanks!!

A couple of questions using adb on an unrooted A716U. Forgive me if these have already been answered, this has me a little frustrated.

1. Is there a way to unlock the oem bootloader or make the item available under developer options? I would like to root but no unlock oem. under developer options

2. in lieu of rooting can I put an application in the system group or grant "root" permissions (such as titanium backup)

3. Will the backup command allow me to backup the rom and recovery img?

Is there a way to unlock the oem bootloader or make the item available under developer options? I would like to root but no unlock oem. under developer options

Not on latest devices I believe, like above Android 6/7.

in lieu of rooting can I put an application in the system group or grant "root" permissions (such as titanium backup)

Kind of, you can grant app the permissions of changing secure settings and some more. Check this and find out if Titanium also allows that. https://www.tapatalk.com/groups/macrodroid/granting-write_secure_settings-permission-via-adb-t2923.html

Will the backup command allow me to backup the rom and recovery img

That internally does backups using adb but not like you think, you can backup to otg or internal storage but not directly to PC. There used to be a command but it does not work anymore : adb backup --twrp inside twrp.

Hey thanks for the list.
I want to install an apk from /sdcard partition. I tried adb shell pm install < path of apk on device > but that resulted in Unable to get size of:/sdcard/app.apk what am I missing?

BTW you need to first copy that app to /data/local then it would install from there. Regular adb install pathToApkInPC.apk also first moves apk there and then install.
